Capacitive Sensors

BCS capacitive sensors for object detection

Reliably detect objects – using a straight-line electrical field

Our capacitive sensors for object detection feature a straight-line electrical field. Using this, they recognize even media with a low dielectric constant at a long distance. These sensors detect liquids as well as solid bodies such as wafers, printed circuit boards, cardboard packaging, stacks of paper, bottles, plastic blocks and boards.

Features

  • Compact designs from Ø 6.5 mm
  • Flat designs or disc shapes with a sensing distance of up to 25 mm
  • Flush installation
  • Plastic and stainless steel designs
  • Economical designs available
  • Adjustable via potentiometer or cable teach-in
  • Plug and cable variations
  • Optionally with IO-Link

BCS capacitive level sensors without media contact

Non-contacting detection of liquids or bulk materials

You want to detect and monitor fill levels in containers, pipes, or tanks while in contact with the medium? This is not a problem for our capacitive level sensors without media contact. They detect the fill level of liquids and bulk materials and deliver reliable results.

A wide variety of models is available for many different applications: especially compact and flat cylindrical, cubic, or disc configurations as well as pressure-rated versions and with a variety of plug and cable variants.

Of particular interest: equipped with our patented Smart Level technology, the capacitive sensors from Balluff compensate for moisture, foam, and adhesion of any kind. That makes the sensors ideal for level measurement of conductive media.

Features

  • For fill level detection of liquids and bulk materials
  • Large selection of configurations and housing materials as well as cost-effective versions
  • Easy adjustment and setup, also via IO-Link
  • Patented Smart Level technology compensates for adhesion, moisture, and foam through glass and plastic walls up to 10 mm thick

BCS capacitive level sensors with media contact

Designed for media-contacting detection of liquids or bulk materials

Our capacitive level sensors with media contact detect the level of granulates, powdery, viscous or liquid media as well as bulk goods in containers, pipes or tanks. Thanks to their great number of variants they can handle a wide range of applications.

Choose from cylindrical form factors, immersibles and versions for hole or flange mounting as well as pressure-rated versions or sensors with different connectors and cables. In addition, their diverse range of housing materials, such as stainless steel, PTFE, and PEEK, ensure the best possible chemical resistance.

Good to know: equipped with our patented Smart Level technology, the capacitive sensors from Balluff compensate for moisture, foam, and adhesion of any kind, and they offer high application reliability.

Features

  • For fill level detection of plastic granules, grains, feed and wood pellets, oils, aqueous liquids, acids, lyes, conductive powders, etc.
  • Large selection of configurations and housing materials as well as cost-effective versions
  • Easy adjustment and setup, also via IO-Link
  • Patented Smart Level technology to compensate for adhesion, foam, and moisture

BCS capacitive sensor heads for switching amplifiers

Small, flexible, robust, and with separate processor unit

Wherever a sensor with integrated electronics would not work optimally due to its environment, the capacitive sensor heads from Balluff offer you the precision to keep your system running. These are suitable for detecting liquid, paste-like, and powdery media – in direct contact or even through up to 4 mm thick container walls made of glass and plastic.

Thanks to the compact design, our solutions work exceptionally well in tight spaces because the electronics are separated from the sensor head.

Features

  • Made of PTFE or stainless steel for very extreme temperatures or for the highest pressure
  • Operation via a separate remote amplifier, optionally with switching signal, analog or with IO-Link
  • Quick, easy, and cost-effective installation
  • Especially environment-resistant and robust variants available

BAE remote amplifiers for capacitive sensor heads

The right setup for every application

Balluff remote amplifiers enable our capacitive sensor heads to be setup and processed easily. Compact signal converters with switching signals, analog values, or IO-Link functionality for top-hat rail mounting are available for this purpose.

Features

  • For simple setting and processing of our capacitive sensor heads with compact, convenient processor or IO-Link signal converter for DIN rail mounting
  • Adjustment possible beyond critical environment conditions
  • Compact configurations and various functional modes

BCS capacitive sensors with special properties

Pressure- and temperature-resistant even in demanding environments

Our portfolio also includes capacitive sensors specifically for high technical requirements, such as for pressure or high temperatures. As self-adhering variants, they adapt very easily to the surface they are to be attached too in a flexible manner. Housing materials such as stainless steel, plastic, or PTFE make them ideal for use in tough environments.

For use at extremely high temperatures or when space is limited, we even offer sensor heads with remote electronics. As a result, these can also be installed in hard-to-reach places and fine-tuned easily. Since their amplifiers are available with switching or analog output or with IO-Link interface, you can use the sensors
across a wide range of applications. Depending on which output you choose, you can use it to detect a limit level, for example, or to set up continuous fill level detection.

Features

  • With stainless steel and plastic housings – also available in PTFE
  • High temperature resistance of up to 250 °C and at 180 °C, pressure-rated of up to 6 bar as well as high pressure-rated for up to 150 bar
  • Sensor heads for use with separate amplifier, IO-Link capable
  • Self-adhering variants for easy and flexible attachment
